Beit known that LCHARLES E. l-IUTCHINGs, each corner, with alaterally-projecting flange a citizen of the United States, residing at7. Attached to the flanges3 andeare-bowed Rochester, in the county ofMonroe and State springs 8, each of said springs being attached 5 of NewYork, have invented new and useful at one end to the adjacent flange andthe Improvementsin Camera-Backs, of which the other end thereof restingloosely against the following is a specification. flange, thearrangement being such that when Thisinvention relates to photographiccamthe camera-back is slipped into place in front eras, and has for itsobject to provide a camof the flanges 3 and at the springs will bear toera with an improved back which is yieldagainst the flanges 6 and holdthe cameraingly movable toward and from the rear end back in closecontact with the rear end of the of the camera-box and is verticallyremovable bellows-frame. therefrom, the arrangement being such thatProjecting laterally from the edge of the a plate-holder may be insertedbetween the back is a projection 9, which is adapted to r5 back and therear end of the camera-box in engage the recessed or cut-away portion 4:of proper position to have cast on the plate conthe flange 3, beforedescribed, so that when tained by the holder the view projected theretheplate-holder has been inserted in position on by the Objective, andwhich also permits a between the back of the camera and the rear of theready removal of the plate-holder and end of the bellows said projectionwill pass 20 the camera-back. into the cut-away portion of the flange,and

To these ends my invention consists in the when the plate-holder iswithdrawn from the features and in the construction, combinacamera theback will be held by said lateral tion, and arrangement of partshereinafter projection against vertical movement,so that described, andparticularlypointedout in the it cannot possibly be withdrawn with the25 claims following the description,reference beplate holder throughfrictional engagement ing had to the accompanying drawings, form'- withthe latter.

ing a part of this specification, wherein- The back 5 is provided with aground glass Figurel isadetailed perspective view show- 11 and with ahinged door12, which is adapting the rear end of the camera and thecamed to close and uncover the ground glass.

When the plate-holder has right angles to formthe flanges 3, providing been inserted and has forced the back of the achamber to receive the back of the camera camera rearwardly in themanner described,

One of the flanges 3 is the projection 9 on theedge of the camera- 5 i cut away or recessed, as indicated at a, forback is forced into the cut-away portion 4 of a purpose hereinafterexplained. the adjacent flange. When the plateholder The numeral 5indicates the back of the is pulled out from the camera, it has atendcamera,which is provided on its opposite verency through itsfrictional engagement with 50 tical edges with laterally-projectingflanges the back to pull the latter vertically out of mo its place; butowing to the fact that the projection 9 upon the insertion of theplateholder has passed into the cut-away portion 4 of one of the flangesit will be impossible to raise the camera-back until the plateholder hasbeen removed therefrom, whereupon under the impulses of the springs 8the camera-back will be forced inwardly, causing the projection to passout of the cut-away flange, and the back may then be readily removed bysliding it out of the camera-boX.

From the foregoing description it will be obvious that while the back isreadily removable from the camera box or casing it is absolutelyimpossible to remove said back until the plate-holder has been Withdrawntherefrom.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a camera, the combination with the camera box or casing havinginwardly-turned flanges at its rear end; of a removable back havinglaterally-projecting flanges and arranged to movably fit within theflanges of the camera-box, said camera-box and said camera back providedwith interlocking means whereby on the insertion of a plateholder,removal of the cameraback is prevented and springs arranged to hold saidback to its seat against the camera-box, substantially as described.

2. In a camera, the combination with the camera-box havinginwardly-turned flanges at its rear end; of a removable back havinglaterally-projecting flanges and arranged to movably fit Within theflanges of the camerabox to receive a plate-holder, springs arranged tohold the back and the plate-holder to their seats, and automatic meansfor preventing the removal of the back until the plate-holder has beenwithdrawn, substantially as described,

3. In a camera, the combination with the camera-box havinginwardly-turned flanges at its rear end; of a removable back providedwith laterally-projecting flanges and arranged to movably fit Within theflanges of the camera-box, springs arranged to hold said back againstits seat in the camera-box, and automatic means for preventing, undernormal conditions, the removal of said back, substantially as and forthe purpose specified.

4. In a camera, the combination with the box or casing havinginwardly-turned flanges at its rear end; of a removable back havinglaterally-projecting flanges and arranged to movably fit Within theflanges of the camerabOX, springs arranged to hold said back to its seatagainst the camera-box, and means made active by the insertion of aplate-holder to prevent removal of said camera-back.

5. In a camera, the combination with the camera-box havinginwardly-turned flanges at its rear end, one of said flanges being cutaway; of a removable back having laterallyprojecting flanges andarranged to fit within the flanges of the camera-box, springs arrangedto hold said back against its rearward seat, said back having alaterally-projecting lip or flange arranged to engage the cut-awayportion of the flange before mentioned to hold the back againstdisplacement, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
